Re: compile error with GNU ARM v4.9.3

GCC support is in "beta" for the BLE 2.3.0.0 stack at this time. The logs that were posted showed it using the BLE 2.1.1.0 stack, if the empty project was actually created with the BLE 2.3.0.0 stack then there is an error in the project generation. If not please create the project using the BLE 2.3.0.0 stack.

The basic problem appears to be that the gcc startup code was not included in the project. In device folder (for example EFR32BG1B) under the CMSIS folder, a link to the appropriate startup_gcc_efr32 .s file should be included (for the example it is startup_gcc_efr32bg1b.s). It can be dragged from the appropriate location to the project folder and added as a linked file (example folder: C:\SiliconLabs\SimplicityStudio\v4\developer\sdks\gecko_sdk_suite\v1.0\platform\Device\SiliconLabs\EFR32BG1B\Source\GCC)
